I sort of did this already.  I grabbed some samples off the Wiki.  My best
recollection is that the lost resolution one was OK, but the higher ones
weren't.  In any case, I'm going to give what you suggest a try and try and
build an HD-PVR capable version of 0.21-fixes first.  One problem I've
already found with that is that the thread where these patches were
mentioned also mentions some manual schema modification in order to support
this patch.  I'm a bit concerned about how to get to 0.22 if I go this

I don't suppose anybody has any debs for a 0.21-fixes + HD-PVR?!? (just to
save me the trouble of doing the builds ;-)

I realize I could watch -commits and -dev and look for a point where the
trunk has mainly stabilized.  However, my point was I'd be perfectly happy
for someone to tell me such a point in the past as well.  I'm assuming that
such points have been reached between now and when VDPAU support showed up.
So if anybody has any suggestions, I'm all ears.  I'm assuming I'm not the
only one in this boat.

Don't forget that if you're going with option 3, you also need to run beta

Good point.  Thanks.
